Section 584.2451 - Supply of water to milk plants1. Water used in milk plants must be obtained from a source approved by the Commission. The lines for the approved sources of water may not be cross-connected with any unsafe or questionable sources of water or any sources of pollution through which the approved supply may become contaminated. The pipes for the approved sources of water must not be connected with any makeup tank, used for such purposes as cooling or condensing, unless the source of water is protected by an air gap or an effective method of preventing backflow.2. Any new, individual system for the supply of water and any system that has been repaired or has become contaminated must be disinfected before being placed in use. Before any samples for bacteriological testing are collected, the system must be flushed with water disposed of as waste to ensure that the system is free of the disinfectant.3. Samples for the bacteriological testing of an individual water system will be taken upon initial approval of the structure or installation of the system and semiannually thereafter, and after a water system has been repaired or altered.4. Water that is recirculated in a cooling system must be obtained from a source which is safe and protected from contamination. That water must be tested semiannually and comply with the bacteriological standards for potable water. Chemicals for depressing the freezing point of water and chemical coolants that are used in cooling systems must be nontoxic.Nev. Admin. Code § 584.2451
